| Abstract: | A general equation of latent heat in differential scanning calorimetry has been derived from considering the temperature gradients within the sample and the general situation in which the heat capacity of the sample has a change during the transition and is a function of temperature. |

| Keywords: | Differential scanning calorimetry (DSC) Latent heat Temperature gradient |
